Christine Sinclair, F – The Canadian women's national team forward still hasn't scored, and Thorns coach Paul Riley has continued to say that Sinclair just needs to get that one goal before the floodgates will open. The Thorns will be hoping that Sinclair can finally notch her first goal of the season Wednesday against the last-place Boston Breakers.

Jessica McDonald, F – McDonald probably had her worst performance of the season Saturday against Sky Blue FC and, with Alex Morgan nearing full health, the forward will need to pick things up against the Breakers. McDonald still leads the Thorns with five goals and Portland will be looking to her as it tries to earn a win on the road in Boston.

Nikki Marshall, D – The defender has been solid in leading a young back line in the absence of veteran center back Rachel Van Hollebeke, but the Thorns have made some key mistakes this season that have cost them. The Thorns left Sky Blue's Kelley O'Hara open on a free kick Saturday and she scored the winning goal as Portland lost 1-0. Marshall will need to lead the back line as it looks to avoid mistakes and have a strong performance in Boston.

BOSTON BREAKERS

Lianne Sanderson, F – To stop Boston, Portland will need to stop Sanderson. The English forward, who formerly played under Thorns coach Paul Riley on the Philadelphia Independence, has two goals and one assist on the season for the Breakers and was voted NWSL player of the week at the end of April.

Heather O'Reilly, M – The U.S. women's national team midfielder has two goals and one assist on the season and leads Boston with 17 shots. The Breakers have relied on O'Reilly to produce much of their offense this season, and if Boston hopes to end a three-game losing streak against the Thorns, O'Reilly will need to have a good performance.

Alyssa Naeher, GK – Naeher leads the NWSL in saves with 34 and has helped keep last-place Boston in games this season with her performance. The Thorns have been getting a lot of scoring opportunities in recent games, but have been unable to convert many of their chances. Portland will have to be on its game to put a ball past Naeher.
